The first picture was taken from a position a considerable distance to the left of the second picture. The profiles of the nearer and further mountains make this obvious. If anything, it makes the retreat of the glacier seem more pronounced.

None of these photos is anything more than the equivalent of anecdotal evidence, without real positions and times, without photos taken in intermediate years (especially dealing with snowfall), and other important background information. I could play this game with almost ANY scene, by just selecting my "before" and "after" pictures carefully.

From my own experience, a picture taken of a field in Minnesota with no snow on a given date in 1980 and another picture showing the same field piled under eight foot drifts on the same date in 2003 would not be that hard to arrange. That's called weather.
